Abstract:

Micro/nano-positioning is one of the key techniques in the domain of micro/nano-manipulation. Compliant micro/nano-positioning systems have been extensively used for precise positioning of microrobotic end-effectors dedicated to ultrahigh precision manipulation and assembly applications with nanometer resolution. It is challenge to develop compliant micro/nano-positioning systems with both large motion range and compact physical design. This work outlines our recent research progress on the design, development and control of compliant micro/nano-positioning systems dedicated to biological cell micromanipulation including microinjection, microgripping, and microprobing. In particular, large-range linear and rotary micro/nano-positioning stages are developed, multi-axis force-sensing microgrippers are created, piezoelectric-driven microinjectors with force sensing and control are introduced, and constant-force micro/nano-manipulation tools are proposed. Perspectives on future work will be discussed.
